摘要
在新集矿混合立井的施工中,采取了分段施工立井贯通新措施,为了确保贯通误差要求,消除系统误差的累积影响,故采用了独立的控制系统,测量定向采用陀螺仪定向,实践表明,贯通的误差值均达到了预期要求,可为类似贯通工程测量提供参考。
A new measure of sublevel driving through was adopted in the construction of the skip and cage shaft of Xinji Mine. In order to reach the required through error and eliminate the influence of accumulative errors, an independent control system was adopted and a gyro directional finder was used for survey orientation. The practice showed that all through error values achieved the desired requirement and can be as reference for similar projects.
